UI fix:
- Close-only modals showing a redundant second close button now use
hideCancel: ReceivedInvoices paid-detail modal (was two identical "Zavřít"
buttons) and PlanCellModal "Den je součástí rozsahu".
- Add modal-duplicate-close test enforcing close-only modals set hideCancel.
Lint: cleared all 68 warnings → 0.
- preserve-caught-error: attach { cause } in ai.service / exchange-rates.
- no-require-imports: package.json version read via fs (APP_VERSION) instead
of require(), avoiding a rootDir-expanding static JSON import.
- react-hooks/exhaustive-deps (11): ref-in-cleanup copies, derived-value
useMemo wrapping, PlanGrid field extraction, stable nextKey useCallback,
AuthContext documented cycle-break.
- no-explicit-any (53): precise route param/Prisma types, generic enrich*()
preserving payload shape, minimal vite module type, frontend body/query-key
types, SystemInfo for Settings.
Refactor (test enablement): shift-form types moved to dependency-free
shiftFormTypes.ts so the print-HTML builders are unit-testable without the
component graph; characterization test pins their output.
Gates: 649 tests pass, tsc -b clean, lint 0. Verified touched flows live
via Playwright (PlanWork CRUD + optimistic cache, warehouse form keys,
Settings system info, invoice detail).
